腾讯混元于4月23日发布并开源Hy3preview语言模型，这是一个融合快慢思考的混合专家模型，总参数295B，激活参数21B，支持256K上下文。作为重建后训练的首个模型，它在复杂推理、指令遵循、上下文学习、代码和智能体等能力上显著提升，是混元迄今最智能的模型。2026年2月，腾讯混元重建了预训练和强化学习基础设施，注重模型实用性。
腾讯发布开源AI模型Hy3Preview，参数达295亿，支持长上下文，在推理、指令遵循和代码处理等方面表现提升，强调实用性、真实评测和高性价比。
腾讯推出新一代AI大模型混元3.0（Hy3），在编程能力方面表现突出。该模型由AI专家姚顺雨加盟后性能显著提升，目前以Hy3preview名义在openrouter上免费开放体验。
